Background Information
Cleavage and polyadenylation specific factor 5, 25 kDa (CPSF5, synonym: CFIM25) is one subunit of a cleavage factor required for 3' RNA cleavage and polyadenylation processing. The interaction of CPSF5 with the RNA is one of the earliest steps in the assembly of the 3' end processing complex and facilitates the recruitment of other processing factors.

Reviews
What customers say
Customers report mixed results depending on application. One user found the antibody performs very well in Western Blot at 1:1000 dilution on nuclear protein extracts, giving strong, clean signals. Another user employed it for immunofluorescence on mouse brain at 1:100 dilution but encountered high background issues that required troubleshooting. Overall, the antibody is well-suited for WB, while IF applications may need optimization to reduce background.
